Story: Maryan Joseph (played by Dhanush) is a fisherman in a village named Neerody. He has an auspicious bond with sea and proudly claims himself as "Kadal Raasa" (King of Ocean). There is Panimalar (played by Parvathy) who falls in love with Maryan and doesn’t shy away in confessing it to him. Maryan is loved and longed by Panimalar but sadly her feelings are not reciprocated. The more Maryan tries to keep Panimalar away from him, the closer she tries to get. This eventually leads to Maryan falling for Panimalar.
